In Brooklyn’s Prospect Heights, this townhouse by Etelamaki Architecture has a spa-like bathroom with mixed materials that include a slate wall behind the double sinks, which are suspended on a teak vanity.

modern vanity with two partial drawers fits snugly into a small space; a lower shelf leaves plenty of room for towels. A concrete countertop and stainless-steel backsplash provide contemporary contrast to the rustic wood drawer fronts.
